Asymmetric C N bond formation was achieved in a highly enantioselective manner by using (OC)Ru(salen)-catalyzed sulfimidation and the subsequent [2,3]sigmatropic rearrangement: treatment of allyl aryl sulfides with p-toluenesulfonyl azide in the presence of a catalytic amount of (OC)Ru(salen) follow
BH, containing iron complexes Fe(q'-HB(H),SCHSR')(CO)(PR,), (3) were prepared by reduction of Fe(q'-CS,R')(X)(CO)(PR& derivatives (2) with NaBH,. The X-ray structure of 3a (R' = R = Me) shows the cis addition of the H-and BH, fragments to the coordinated dithioformate C-S bond and that one B-H bond
